The reading passage and lecture hold contradictory opinions on two possible explanations of the decline of the sea otter.
To begin with, the passage supports the pollution hypothesis by saying that there were sources of pollution along the coast and the polluted water was harm to otters' life. However, the speaker says the pollution hypothesis is weaken by the fact that there was no dead otter washed up on shore. On the other hand, no dead otter on the shore reflected the predation hypothesis. The predator ate the otter immediately so there was no dead otter on the shore.
In the second place, the passage states that otters are not the only species that declined. Whatever affected otters also endangered other sea mammals. And predators like orca only hunt large prey like whales. The speaker refutes this opinion by arguing that the whale disappeared at the time. Orcas have to change eating habit. They targeted at smaller prey like otters and seals.
Lastly, the passage advocates the pollution hypothesis by suggesting that uneven pattern of otter decline was caused by the uneven concentrations of pollutants. The speaker disagrees with this view. She says that less decline of otters was because orcas cannot access where they located, like shallow or rocky places.
